Five days after a fire that destroyed an estimated 70 homes in the Midwest City/Choctaw area, fire investigators are still not sure if the search for an origin will turn into a criminal investigation. Midwest City Fire Marshal Jerry Lojka said his department is confident the fire was intentionally set, because investigators have ruled out any normal accidental causes. But that doesn’t mean the spread of the fire was not accidental, he said. “Any fire investigation involves a process of elimination,” Lojka said. “And once you can eliminate the accidental causes it allows you to move on to something else. This was a people set fire. The question is exactly how and why. Honestly, it may have been a mistake, but we don’t know that yet.” Lojka said his investigators continue to work with police and independent insurance investigators to track down leads on the origin of the fire, but that process could take some time. “Since we haven’t established the fact that this is a criminal investigation, there are certain things we’re not going to do until that has been determined,” he said. “We’re just really trying to follow up leads now before we determine where we want to go.” Lojka said he could definitively say that there was no welding or any other industrial activity that could have started the fire, but there were numerous other possibilities, including everything from setting a fire for cooking to lighting incense at a “hideaway.” “If they were people who were hanging out there for any reason in an abandoned mobile home, motor home or a bus or whatever else that was burned out there, they may have lit a fire and it got out of control,” Lojka said. “That was intentionally set but without malice. “Somebody did not accidentally flick a cigarette out there, because it’s too far from a road. People were there. They were engaged in an act that would have ignited the fire. And they did it intentionally but we don’t know what their intent was,” he said.
